Alongside with the name, email, message, etc. I want to send a field that'll show up in my mailbox with an incremental number. For instance:
Name: Alex
Mail: alex@...
Message: Hi.
Email Number: 0001 (then 0002, 0003 and so on) <-- this is what I'm aiming to. Is it possible?
I didn't understand your question fully, but you might be looking for something familiar.
$number=0001;
$msg="Hi. "."Email Number: ". $number;
mail('[email protected]', 'My Subject', $msg);
